For these pictures, we used a camera at the regular settings but the one of the settings was set to infinity to capture the wave itself. We set the Hertz to 48.7 and measured the wave itself. The wavelength was .725 meters long. Take the Hertz and multiply it by the wavelength. So that would be .725m*48.7Hz and that equals 35.31m/s. That was how fast the waves were traveling at 48.7Hz.
